w (is-BOTTLE CLOSURE.

Application filed November 29, 1922. Serial No. 608,898.

To allwhom it may concem:

Be it known that LJOHN W. PETERMAN, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in a Thermos-Bottle Closure, of which the following is a specification.

An object of my invention isto provide means for positively retaining corks and similar closures upon thermos bottles and the like.

Another object of m invention is to provide a simple and e cient device for the purposes stated.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which- Fig. 1 is a sectional view on line 1-1 of Fig. 2 showing a device embodying my invention.

Fig. 2 is a sectional view on line 22 of Fig. 1.

i The thermos bottle-comprises the ordinary inner casing 3 supported by an outer casing 4. The inner casing 3 has a mouth 5 for which a stopper or cork 6 forms a 010- sure. A cap or cup 7 is removably mounted on the outer casing 4 by means of the 80 complementary threads 8. A spring 9 carrying at its opposite ends the discs 10 and 11 is contained within the cup 7. The upper disc 10 is of a diameter substantially equal to the diameter of the bottom of the cup, and the spring is mounted on the discs by any suitable means-such as by being soldered thereto so as to extend in co-axial alignment with the axes of the discs. The disc 11 is of a diameter substantially equal to to the diameter of the cork or stopper 6.

The disc 11 carries a spiral cork screw 12 which is seated in the cork 6.

The spring 9 together with the discs 10 and 11 are. mounted upon the cork 6 by means of the spiral screw 12. When the cork 6 is inserted in the mouth of the bottle 3, the disc 10 assumes a position in substantial circumferential alignment with the inner surface of the bottom of the cup. When the cup is secured upon the outer case 4, the compression directed upon the spring 9 precludes the cork 6 from leaving its seat upon the bottle 3. The positive connection between the disc 11 and the cork 6 precludes any separation of the cork and the spring, thereby affording a positive and secure seating of the cork upon the bottle 3.

What I claim is:

1. The combination with. a closure such as a cork, of a spring, discs carried by the 0 spring at its opposite ends, and a cork screw carried by one of the discs and extending into the closure whereby to positively fix the closure and the spring upon one another.

2. A closure device of the class described comprising a vessel having an opening, a closure for the opening-of the vessel, a pair of discs, means yieldingly' spacing the discs from one another, means carried by one of 7 the discs for positively securin said disc and the closure upon one anot er, and a cap for moving the second disc against the yielding resistance of the disc spacing means.

In testimony whereof, I have hereunto subscribed my name this 25th da of November, 1922.

JOHN W. PETERMAN.
